by John Walker January 4, 1994 Fly's Eye The University of Utah operates a cosmic ray detector called the Fly's Eye II, situated at the Dugway Proving Ground about an hour's drive from Salt Lake City. The Fly's Eye consists of an array of telescopes which stare into the night sky and record the blue flashes which result when very high energy cosmic rays slam into the atmosphere. From the height and intensity of the flash, one can calculate the nature of the particle and its energy. On the night of October 15, 1991, the Fly's Eye detected a proton with an energy of 3.2±0.9×1020 electron volts.[1,2] By comparison, the recently-canceled Superconducting Super Collider (SSC) would have accelerated protons to an energy of 20 TeV, or 2×1013 electron volts—ten million times less. All evidence points to these extremely high energy particles being protons—the nuclei of hydrogen atoms. Microbial Mass How Fast? How fast was it going? And thus, approximately: v = 0.9999999999999999999999951 c Quicktime
Alcubierre Warp Drive Time TravelAn Alcubierre Warp Drive stretches spacetime in a wave causing the fabric of space ahead of a spacecraft to contract and the space behind it to expand. The ship can ride the wave to accelerate to high speeds and time travel. The Alcubierre drive, also known as the Alcubierre metric or Warp Drive, is a mathematical model of a spacetime exhibiting features reminiscent of the fictional "warp drive" from Star Trek, which can travel "faster than light" (although not in a local sense - see below). The key characteristics of the application of Alcubierre warp drives for time control and time travel are presented in the picture below. This is followed by more detail describing the effect below. Alcubierre Warp Drive Description In 1994, the Mexican physicist Miguel Alcubierre proposed a method of stretching space in a wave which would in theory cause the fabric of space ahead of a spacecraft to contract and the space behind it to expand.

La vitesse de la lumière et Einstein dépassés par une particule?«Totalement inattendu», «étonnant»... Les physiciens n'en croyaient pas leurs instruments mais ils pensent bien avoir mesuré une particule dépassant la vitesse de la lumière, pourtant considérée comme une «limite infranchissable» dans la théorie d'Einstein. Selon les mesures effectuées par les spécialistes de l'expérience internationale Opera, des neutrinos - particules élémentaires de la matière - ont parcouru les 730 km séparant les installations du CERN à Genève du laboratoire souterrain de Gran Sasso (Italie) à une vitesse de 300.006 kilomètres par seconde, soit 6 km/s de plus que la vitesse de la lumière. «Autrement dit, sur une course de fond de 730km, les neutrinos franchissent la ligne d'arrivée avec 20 mètres d'avance» sur la lumière si elle avait parcouru la même distance à travers l'écorce terrestre, précise le CNRS. «Je ne m'attendais pas du tout à ça» Appels à la prudence Si la mesure est confirmée, ses implications défient encore la compréhension.
World's best info-graphics show us the value of body parts, surname distribution and what makes a great novelInformation Is Beautiful Awards celebrated the best data graphicsGraphics showed anything from the monetary value of a human brain to the most common Alaskan surnames By Graham Smith Published: 15:55 GMT, 2 October 2012 | Updated: 16:29 GMT, 2 October 2012 A map of the human body that lists the value of each body part; a map of the U.S. that marks the most popular surnames; and a graphic that shows what plot details make a great novel. These were just three of the entries at the Information Is Beautiful Awards ceremony in London last week, celebrating the most ingenious methods of making numbers and facts visually interesting. The body parts map provides the price in sterling for every limb, organ and gland based on the growing industry of human tissue recovery. The researchers calculated the values from prices charged by human tissue recovery agencies that collect body parts for research. If you could do away with your brain altogether, expect to be paid £10,707 for all its parts.
Atomic Test Effects in the Nevada Test Site RegionThirty-one atomic fission weapons, weapon prototypes, or experimental devices were fired in Nevada from January 1951 to January 1955. All were relatively small in explosive power. They ranged from less than one kiloton up to considerably less than 100 kilotons. (A kiloton is equal to 1,000 tons of TNT.) The forces released by test detonations in Nevada are very small compared to the tremendous forces released by the large fission and hydrogen weapons tested in the Pacific. So-called "H-bombs" are not tested in Nevada. Despite their relatively low yield, Nevada tests have clearly demonstrated their value to all national atomic weapons programs. Each Nevada test has successfully added to scientific knowledge needed for development and for use of atomic weapons, and needed to strengthen our defense against enemy weapons. An unusual safety record has been set. There were instances of property damage from blast, such as broken windows. Exposure to Flash Past Experience With Flash The U.

Website of Air Photo Service Co.NASA: Don't Let This Happen to Your PlanetPhysics envyIn science, the term physics envy is used to criticize a tendency (perceived or real) of softer sciences and liberal arts to try to obtain mathematical expressions of their fundamental concepts, as an attempt to move them closer to harder sciences, particularly physics. Evolutionary biologist Ernst Mayr discusses the issue of the inability to reduce biology to its mathematical basis in his book What Makes Biology Unique?. Noam Chomsky discusses the ability and desirability of reduction to its mathematical basis in his article "Mysteries of Nature: How Deeply Hidden." See also Notes Jump up ^ For example, Eugene Wigner remarked "The miracle of the appropriateness of the language of mathematics for the formulation of the laws of physics is a wonderful gift which we neither understand nor deserve References Chomsky, N.
